Take everything you have ever heard, read, or seen about cover letters and throw it out the window! That's right, 99.44 percent of the information about cover letters is useless. Contrary to some of the more fashionable books on job search, no one ever got a job because of a spiffy (or "perfect") cover letter. Cover letters are extremely limited in value, even when properly used. But they do have their place, when used properly.
